Answer:

  11 feet

Step-by-step explanation:

Let L and W represent the length and width of the patio. Then ...

  L = W + 10

  P = 2(L + W)

Substituting for the known values, we have ...

  64 = 2((W +10) +W)

  64 = 4W +20 . . . . simplify

  44 = 4W . . . . . . . . subtract 20

  11 = W . . . . . . . . . . divide by 4

The width of the patio is 11 feet.

Answer:

8 seconds

Step-by-step explanation:

d(t)=400

4t^2+18t=400

4t^2+18t-400=0          subtract 400 from both sides

2t^2+9t-200=0           divide by 2 on both sides

x=8; -25/2                     solve using quadratic formula

Answer:

640

Step-by-step explanation:

200 divided by 25 = 8

which means Kris can run 8 meters per second. 8 times 80 equals 640.

Answer:

x=0

Step-by-step explanation:

Answer:

20

Step-by-step explanation:

8x=6x+5 (subtract 6x from both sides)

2x =5 (divide by 2 both sides)

x=2.5

8x= 8*2.5 = 20 (substitute 2.5 for x)

or 6x+5 = 6(2.5)+5 = 20 (substitute 2.5 for x)

Answer:

The indifference point is 200 miles

Step-by-step explanation:

First, we need to establish the total cost formula for each company:

Pack and Go:

Total cost= 39.95 + 0.45x

x= miles driven

U-Drive:

Total cost= 59.95 + 0.35x

x= miles driven

Now, we equal both formulas and isolate x:

39.95 + 0.45x = 59.95 + 0.35x

0.1x = 20

x= 200 miles

The indifference point is 200 miles

Answer:

A is answer 1/ 39.95 + .45x = 59.95 + .35x

B is answer 3/ miles driven

C is 3 /200

Answer:

The area is 7200 square feet and the perimeter is 360 feet.

Step-by-step explanation:

Formulas (for easier reference):

Area of rectangle: length × width

Perimeter of rectangle: length + width + length + width

We can just apply the formulas.

Area of court = 120 × 60

                      = 7200 square feet

Perimeter of court = 120 + 60 + 120 + 60

                               = 360 feet

Answer:

The second train speed is 356.4 miles per hour

And, the first train speed is  361 miles per hour

Step-by-step explanation:

The computation of the speed of each train is as follows

Given that

The Sum of the speed of two trains is 717.4 miles per hour

Let us suppose the second train speed be x

So for the first train, the speed is x + 4.6

Now the equation is

x + x + 4.6 = 717.4

2x + 4.6 = 717.4

2x = 717.4 - 4.6

2x = 712.8

x= 356.4

Therefore the second train speed is 356.4 miles per hour

And, the first train speed is = 356.4 + 4.6 = 361 miles per hour

1/4 = 18
